While the half-life of nicotine is approximately 2 hours, its primary metabolite, cotinine, can be detected in the body for much longer, sometimes for several weeks. This variance is key to understanding how long does it take for nicotine from a vape to exit your body and affects various types of nicotine tests.

While tobacco plants contain small amounts of cotinine, up to 80% of the cotinine found in a tobacco user's body is produced by the liver after exposure to nicotine. This fact reveals the key difference behind the question: **is cotinine present in cigarettes?** The answer is that cotinine is a byproduct of nicotine metabolism, and its presence is a marker of tobacco use, not a primary ingredient in cigarettes.

An estimated 70-80% of nicotine is converted into cotinine by the body, making cotinine the primary biomarker for nicotine exposure. This critical metabolic process is key to answering the common question: **Can cotinine be found in vapes?**

Cotinine, the primary metabolite of nicotine, can accumulate in the body to levels much higher and for longer durations than nicotine itself. This raises a key question for researchers and health professionals: Does cotinine have psychoactive effects, or is it merely an inert byproduct of nicotine metabolism?

Approximately 80 to 90 percent of nicotine is metabolized into cotinine, which serves as a primary biomarker for tobacco and nicotine exposure [1.2.1, 1.10.1]. Understanding what is the life of cotinine in the body is crucial for health assessments and smoking cessation programs.

Cotinine, a major metabolite of nicotine, has a half-life of about 20 hours in the body, which is significantly longer than nicotine's few hours. This stability makes it an excellent biomarker for detecting tobacco use or secondhand smoke exposure. However, many health risks and side effects are mistakenly attributed to cotinine itself rather than the underlying nicotine exposure it indicates.

With a significantly longer half-life than nicotine, cotinine is the preferred biomarker for detecting tobacco use. This detailed guide answers the question of **how quickly do cotinine levels drop**, exploring the factors that influence its clearance from the body.

Over 70% of nicotine absorbed by the body is converted into cotinine, its main metabolite [1.2.3]. The pressing question for many is, **what drug has cotinine in it?** The answer is that no currently marketed drug contains cotinine as an active ingredient.

Nicotine from a product like a 6mg ZYN pouch is metabolized by the liver into cotinine, which has a significantly longer half-life of 16–19 hours compared to nicotine's 1-2 hours [1.2.1]. This article explains how long does the nicotine from a 6mg ZYN stay in your system.

With an average half-life of about 20 hours, cotinine remains in the body long after the parent compound, nicotine, has been cleared. This is why a person can test positive for cotinine even when a nicotine test is negative, and it reveals that you can get cotinine without nicotine present. The extended detection window makes cotinine a far more effective biomarker for assessing recent nicotine exposure than nicotine itself.
